Postprandial blood glucose generally refers to 2 hours postprandial blood glucose, the normal value of 2 hours postprandial blood glucose should be less than 7.8mmol/L, so 2 hours postprandial blood glucose 10mmol/L is out of the normal range. For the general population is relatively not serious, but should be taken seriously, for diabetes and gestational diabetes is more serious. 1. General population: if the general population, currently found that the 2-hour postprandial blood glucose is more than 10mmol / L, it is considered abnormal, belonging to the manifestation of high blood glucose, but does not meet the diagnostic criteria for diabetes, belonging to the glucose tolerance abnormalities, the situation is not serious, but need to pay enough attention, so as not to develop into diabetes. 2. Gestational diabetes: Gestational diabetes patients with 2 hours postprandial blood glucose control in more than 10mmol / L, considered unsatisfactory, the condition is more serious, if you do not reduce blood glucose in a timely manner, it will have an impact on the embryo, resulting in abnormal embryonic development, or cause intrauterine asphyxia. 3. Diabetes mellitus: the non-fasting blood glucose target value of diabetes prevention and control guidelines is ≤10.0mmol/L. 2-hour postprandial blood glucose control is more than 10mmol/L, which is unsatisfactory, and in the case of poor control, the blood glucose may continue to rise and diabetic complications may occur.
